    Here's a video showing you how to make an electric bell.
    An electric bell is a device that converts electrical energy into kineticenergy and then into sound energy. An electric bell has anelectromagnet in front of which an iron armature is adjusted. Its one endis fixed, while the other end is connected with a hammer which ismoveable. Nearby the hammer, a gong is placed in such a way that thehammer can beat on the gong. When the switch is turned on, theelectromagnet attracts the armature. Due to this, the hammer strikesthe gong and the bell rings. As soon as the armature is pulled by theelectromagnet, current in the circuit is automatically switched off. Inthis situation, the electromagnet loses its magnetism and it won't attractthe armature thus armature returns to its original position. The circuit isnow completed and current flows in the circuit. The cycle is repeated
    again and again to ring the bell till the switch is on Don't forget to subscribe our channel:
